Here we answer the question: "What two numbers multiply to -938 and add up to -127?"
The answer to your question is:
-134 and 7
Below we illustrate and prove that -134 and 7 multiply to -938 and add up to -127:
-134 × 7 = -938
-134 + 7 = -127
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 127x - 938 = 0
If so, the solution to factor the quadratic equation above is:
(x - 134 ) (x + 7)
To summarize, since -134 and 7 multiply to -938 and add up -127, you know that the following is true:
x2 - 127x - 938 = (x - 134 ) (x + 7)
